material consists merely of the base of a plant, without flowers, 

 and much eaten by goats, but the leaves exhibit the stiff hairs 

 and strong tubercles so characteristic of E. Auberianum, and there 

 can be little doubt as to the identification. It is to be hoped that 

 the species still survives in this locality. 



Echium Wildpretii and E. Perezii are characterised by a 

 strictly actinomorphic rose-coloured corolla, and long-exserted 

 straight filaments, which radiate regularly from its mouth, 



E. Auberianum is unknown in a living state; Webb and 

 Berthelot described the corolla as blue, but this was presumably 

 from dried material. The corolla appears to be very slightly 

 zygomorphic; the three posterior stamens are included, and the 

 two anterior are shortly exserted. 



It should be stated that the foregoing notes are the result of an 

 investigation commenced in 1912 on the instigation of Dr. Perez, 

 who has sent dried specimens and photographs of E. Wildpretii 

 and E. Perezii to Kew, and afforded valuable assistance in other 



directions.
